Effects of administering various blood serum constituents on gamma globulin levels of baby pigs

SummaryData have been presented which show that porcine gamma globulin, porcine and bovine serum solids and cowscolostrum do not cause a marked or consistent response in the serum gamma globulin level of one-day-old pigs when administered orally. However, parenteral administration of porcine gamma globulin gave a response which approached that obtained with nursing pigs. The inclusion of trypsin inhibitor with orally administered porcine gamma globulin and bovine serum solids did not affect the serum gamma globulin level.
